Application filed August 30, 1910. Serial No. 579,750.

To all whom it may concern:

Be it known that I, GEORG WIRTH, a citizen of Germany, residing at Augsburg, Kingdom of Bavaria, German Empire, have invented certain new and useful Improvements in Machines for Making Cigar and Cigarette Holders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention refers to a device for manufacturing cigar and cigarette tubes or holders and the like of paper.

The essential feature of the present invention is that the mouth-pieces contained in a suitable receptacle are first arranged by mechanical means and then singly and automatically brought into alinement with and up to the winding mandrel.

In the accompanying drawings different forms of construction of the device are shown.

One form of construction is shown in Figures 1 and 1 in plan view and in Fig. 2 in a front view. Fig. 3 showsaposition during the working of the device and Fig. 4 a plan view and section of a detail. Figs. 5, 6 and 7 show in a side view, plan and end view respectively, a modified form of construction of a detail. Figs. 8 and 9 also show a form of construction of a detail in a side view and section along the line AB,

Fig. 8, respectively.

The device according to Figs. 1 to 4 consists mainly of the feeding-device I, the turningdevice II and the winding-device III. The feeding-device I, which is arranged atthe end of the cast iron frame 9 above the turning-device II, consists of a trough-like receptacle 1 (Figs. 1 and 2) merging into an angular trough 2. The trough 1, arranged at a suitable slant, receives the mouth-pieces, which are thrown into it in disorder. An axle 3,carried by the bearing-piece 9, and actuated from the shaft 13 of the turning-device through the cranks and link 4, 4 (Fig. 2), projects into the trough 2. At the end of said axle 3 is arranged in the central plane of the trough 2 a gripper 6, the jaws or cheeks of which are kept closed by means of a spring. Said gripper is provided at its front end with a coverplate 7 conforming to the section of the groove 2. The latter at its front end merges into the arc of a circle and is provided with a sliding-piece 8, having at its end the knife 50. This latter, as also the curved sliding-piece 8, is in the path of the gripper 6, so that the jaws of the latter, as soon as they come in contact with said knife 50, are separated by it. On the knife 50 rests the end of an angular trough 51 (Figs. 2 and 4), pivotally connected at its other end at the point 52 to a trough 10 of the turning-device. The angular trough 51 has at the end nearest the knife 50 recesses 53, through which the gripper can pass. Said trough 51 rests with its tongue 54, which must be narrower than the knife 50, on the latter. The gripper rotates in a path in tersecting the end of the trough 51. The lower part of the trough 2 is slightly inclined and is also provided with recesses 55 (Fig. 1), limited on the inner side by two lips 56, 57, of unequal width. The cheeks of the gripper 6 can pass without hindrance through the recesses 55; the lips 56, 57 prevent the mouth-piece 5, from dropping out of the trough. The plate 7 of the gripper is also provided with slits, not shown in the drawing, so arranged that said plate cannot be held fast by theknife 50. In the same plane with the trough 51 is arranged an inclined trough 10, into which the mouth-pieces are fed, one by one, from the feeding-device.

The turning device II consists of a frame 9 of cast-iron or the like, provided at the side with three inclined troughs 10, 11 and 12; the trough 10 is so situated that the mouth-piece, coming from trough 51 of the feeding-device, can fall unhindered into it. The second trough 11 is arranged below the end of trough 10 and approximately parallel with the same. The third trough 12 is arranged approximately at right-angles to the other two troughs. All four troughs, namely, 51, 10, 11 and 12 lie in the same vertical plane.

In the frame 9 is arranged a shaft 13, rotated in the direction of the arrow from the principal shaft 14 and operating the axle 3 of the feeding-device by means of the crank-gear 4, 4. At one end of said shaft 13 is situated a gripper 15, exactly above the center of the trough 12; the two halves of this gripper are kept closed by a spring arranged at the pivot-point 16. The

free arm of the gripper 15 is bent to form a hook 17, which'during the rotation of the shaft 13 and gripper 15 is arranged to abut against a lug 18, whereby the gripper is opened. At the other end of the shaft 13 is situated a cam-disk 19, curved forward at its end 20. When shaft 13 is rotated the disk 19 presses against the roller 21 of the axially movable mandrel 22, the latter being carried by the frame 9 and having an end 23 of square section. This mandrel 22 is so arranged that it can slide past the end of the trough 10 which is provided with a narrow tongue 24. The mandrel 22 is normally pressed away from the trough 10 by the spring 25 and can only approach said trough when shifted by the cam-disk 19. The frame 9 further carries two shafts 26, 27, having at their ends arms 28, 29, which in the posit-ion of rest almost reach to the bottom of the trough 10. These shafts 26, 27 are further provided with lever-arms 30, 31, resting on-cams 32 and 33, respectively arranged on the shaft 13, said cams being adapted to raise the lever-arms 30, 31 and thus to shift the arms or tongues 28, 29, moving them slightly out of the trough.

The'winding-device III (Fig. 2) contains a trough-like receptacle 34, which is of such a size that only the end of the mouth-piece intended to receive the paper projects out of it. .This receptacle is arranged on a mandrel 35, reciprocated by the eccentric disk 36 keyed to the principal shaft 14. Below the receptacle 34 is arranged another receptacle 37, also trough-shaped and larger than the first; this receptacle 37 is raised by the cam 38 at the moment that a mouth piece drops into the smaller receptacle 34, so that said mouth-piece cannot be thrown out of the said smaller receptacle 34. In order to insure the proper position of the mouth-piece, the trough 37 is provided with a closed end 39.. In front of the receptacles 34 and 37 is situated at a suitable distance the conical winding-mandrel 40, actuated by the principal shaft of the machine in know manner. uated a movable feeler 41, which is pressed against the mouth-piece in the trough 34 during the process of winding, so that said mouth-piece retains its proper position. This feeler may for instance, as shown in the drawing, consist of a rod or pin 41, pressed by a spring 42, and adapted to be movedtoward the mouth-piece during winding by the toothed segment 43, being at other times pressed back by the spring 42. The principal'shaft 14, driven by a pulley44, actuates all parts of the device.

The manner of-working .is as :follows: From the trough 1 the mouth-pieces glide of. their own accord into the inclined portion of the trough 2; since thelatter is an- Behind this mandrel is sitgular in section, only one mouth-piece can come to lie on the tongues 56,57 at one and the same time. This mouth-piece 5 rests against the end of the sliding piece 8 and remains thus until the gripper 6 leaves said sliding-piece; As soon as this occurs, the

jaws of the gripper 6 close over the mouth:

piece 5,carrying it into the position shown in the drawing by dotted lines at 5 in Fig. 2. At the same time the plate 7 holds back any further mouth-pieces, which may have followed the'first, out of the trough 2; As soon as the jaws of the gripper 6 meet the knife 50, they are separated by the latter, and the mouth-piece 5 is again released. Said mouth-piece then falls into thetrough 51, which is then raised by any suitable means, so that the mouthpiece can slide, without turning over, into the trough 10 of the turning device. As soon as this occurs, the trough 51 is again lowered, the gripper 6 again picks up a new mouth-piece, lifts it into the trough51, and so on as before. In the trough 10 the mouth piece slides downward until it meets the arm 28 and is thus brought to rest (Fig. 2). When the shaft 13 rotates, the cams 32, 33, lift the levers 30, 31 of the shafts 26, 27, so that the tongues 28, 29 are also raised and the mouth piece can slide farther down in the trough 10. But at the same time the cam-disk 19, 20 presses the mandrel 22 against the end of the trough 10, so that the mouth-piece abuts against the square end 23, as shown in Fig. 2; the mouth-piece can have either of two positions, since the end with the rim or bead may be either at the top or the bottom.

Two methods of operation are now possible, depending upon the position of said rim. If the mouth-piece in question takes up the position shown in Fig. 2, 45, in

whichthe rim is at-the top, the gripper 15, being moved toward the mouth-piece by the shaft 13, will meet with no resistance on the smooth surface of said mouth-plece, and

will continue its rotation without engaging the mouth-piece. The mandrel 22 hasin the mean time been released by the curve-disk 19, 20 and returned to its position of restby the spring 25, so that the gripper does not strike against the end of said mandrel. The arms, 28, 29 as already mentionedfhold' the mouth-pieces in position, so that these cannot slide farther down. The cams 32, 33

are so arranged, that the lower lever 31 is actuated somewhat earlier than the other lever 30. Thus the further rotation of the shaft 13 will lift the lever 31, so that the tongue29 releases the lower mouth-piece 45.

The latter then slides downward, enters the piece, after the abutment 23 of the mandrel has been withdrawn, and during the time the gripper l5 acts. If it were not for the lower tongue the mouthpiece would immediately drop into the trough 11.

The second mode of operation is shown in Fig. 3, the rim end of the mouthpiece being in this case lowermost and resting against the square end 23 of the mandrel 22. When now the gripper 15 moves along the surface of the mouth-piece 46, it engages with the rim or raised edge at the end of said mouth-piece, and carries it into the position shown by dotted lines, namely 46. At the same time the hook 17 of the gripper strikes against the projection 18, causing the gripper to open and to release the mouth-piece, which latter now falls into the trough 12 and glides into receptacle 34.

Since the gripper 15 has turned the mouth-- piece through an angle of nearly 180, it will be obvious that the mouth-pieces will now again occupy the position 45 in the receptacle 34, that is to say, the end without the raised edge will be nearest the winding mandrel40. Thus the turning-device II always gives the mouth-piece the correct position for winding, independently of the position it may occupy in trough 10.

It is to be noted that the tongue 29 serves to merely hold the mouth-piece while the abutment 23 is withdrawn, and while the gripper 15 is traveling downward over the mouth-piece at that time held under the tongue 29. If the beaded end of the mouthpiece is downward the gripper 15 engages the said bead and draws the mouth-piece from under the tongue 29 which engages the said mouth-piece very lightly. If, however, the beaded end of the mouth-piece is upward the gripper 15 does not draw the mouth-piece from under the tongue 29, but passes off and leaves the mouth-piece still held by the tongue 29, which thereafter is lifted to relieve the said mouth-piece.

The further operation of the machine is as follows: As soon as a mouth piece falls into the receptacle 34, the larger receptacle 37 is raised, so that the mouth-piece cannot jerk out of the receptacle 34; as soon as the correct position of the mouth-piece is assured, receptacle 37 is again lowered. Now the eccentric-disk 36 moves receptacle 34 forward until the mouthpiece takes 11 the dotted position 47 in front of the winding mandrel 40. The paper strip 48 is now wound onto and gummed to the mouth piece. During the process of winding the feeler 41 holds the mouthpiece so fast, that it can be turned but cannot shift its position otherwise. When the paper tube is finished, the feeler 41 is removed and the receptacle 34 is moved back to its initial posit-ion by a suitable spring (not shown), the rotation of the eccentric permitting this, a new mouth-piece falls out of the turning-device, and the above described operations are repeated, and so forth. In this form of the winding-device it may happen that gum or other adhesive means may remain in the receptacle 34, so that the mouthpiece is held by or adheres to the walls of said receptacle, thereby taking up a slanting or false position, so that the end of the mouth piece is not in alinement with the winding mandrel 40. This disadvantage is remedied in the form of construction shown in Figs. 5 to 7, in which the receptacles 34 and 37 are replaced by other improved means. The mandrel 35 is again reciprocated by the eccentric disk 36, and has at its free end, instead of the receptacle 34, a piece 58, one part of which is formed as a triangular trough 59, open in front and at the top, and preferably separated from the bodyof the piece 58 by a slit 60. To the body of the piece 58 abracket 61 is attached, on which is mounted the two-armed lever 62, 63, pivotally mounted on the axis 64. The upper arm 62 of said lever is bent so that its cheek end 65 can project into the trough 59. The cheek 65 is provided at its lower edge with a circular recess becoming wider toward the rear, that is to say, of conical form. A spring '67 or similar means tends to press the check 65 into the groove 59.

The method of operation is as follows: A mouth-piece falls out of the trough 12 (Fig. .2) into the trough 59, the piece 58 being carried forward at the proper moment by the eccentric 36 (Fig. 2); the mouth-piece 45 will occupy the position shown in Fig. 5. During the falling of the mouth-piece into the trough 59, the check 65 must be removed from the trough, which is accomplished by a pin 68' (Fig. 7) actuated by the winding mechanism, which pushes the lower arm 63 of the two-armedlever in the direction of the arrow until the trough 59 is free. As soon as a mouthpiece has fallen into the trough, the pin 68 is automatically returned, and the cheek 65 under the influence of the spring 67, is returned into the trough 59, where it presses the mouth-piece against the sides of the trough, thus holding it fast. It will be apparent that the mouth-piece 45 now lies exactly in line with the axis of the winding mandrel, the trough 59 being so formed as to attain this result. As soon as the mouth-piece comes in contact with the winding mandrel, the whole contrivance is again moved backward, leaving the mouthpiece on said mandrel. The separation of mouth-piece 45 from the trough is greatly facilitated by the conical form of the recess 66 of the cheek 65 which prevents the raised edge or bead of said mouth-piece engaging with said check.

The contrivance represented in Figs. 8

and'9 may be used with advantage for winding mouth-pieces which are not all of uniform diameter, or which are not quite circular in form; in some cases this cont-rivance may also be used in place of the feeler device 41, 42, 43 of Fig. 2. However, it is preferably used together with the said feeler device.

In Figs. 8 and 9 the already wound paper tube 48 is still on the winding-mandrel 40, 47 being the mouth-piece. In order to insure that this mouth-piece 4:7 is in any and every case properly pressed against the paper strip used to form the tube 48 an approximately T-shaped piece 69 is arranged below the winding-mandrel, said piece 69 being adjustable both upward and clownward and also rotatable about an axis 70. At one end this piece 69 is provided with a vertically adjustable plate 71, situated in a recess 72 of said T-piece. The plate 71 is arranged on a pin 73, having at its lower end a foot the spring 74 tends to push the plate 71 upward. For the purpose of winding the cigar-tube the T-piece is so adjusted, that its upper surface is approximately parallel to the lower edge of the winding mandrel, so that the adjustable and springepressed plate 71 rests against the part of the mouthpiece 47 which is intended for the reception of the paper tube. \Vhen the paper strip is now wound onto the mouth-piece 47, said plate 71 will continually press the strip against said mouthpiece, whatever shape it may possess. The T-piece 69 is provided with a lateral plate 7 6 which prevents the plate 71 from being drawn too much to one side by the strip of paper during the process of winding.

It will be obvious that other forms of construction of details of the contrivance may be introduced, without in any way departing from the essential features of the invention. For instance, instead of the feeding device I a receptacle may be substituted, into which the mouth-pieces are introduced, either in order or in disorder and from which they are carried to the trough 10 by a drum provided with longitudinal grooves. Also the turning device may be modified, the essential feature being that the mouth-pieces always reach the winding-device III in the same position.
